Email them the moment it's back
When a product sells out, a notify-me form appears on its page. The moment you restock, everyone waiting gets an automatic email with a link straight to it — sent in the background, so it scales without timing out.

What it does
Built for real WooCommerce stores
Restock email
Restock, and everyone hears about it
Add stock anywhere — the product editor, a CSV import, an ERP or API sync, WP-CLI. The plugin queues the waitlist in Action Scheduler and emails everyone in background batches of 50, with a link straight to the product.
- Each batch re-checks the product is still in stock before sending
- Tokenized one-click unsubscribe in every email
- Sent via
wp_mail/ your own SMTP — no third party
Subscriber list
See exactly who is waiting
Every signup lands in a per-product list in wp-admin — with KPI cards for waiting, pending confirmation and notified, status filters and email search. No more guessing whether the demand exists.
- KPIs at a glance: waiting · pending confirmation · notified
- Filter by product or status, search by email
- One-click CSV export (Pro)
Your rules
Tuned from one settings screen
Double opt-in, consent checkbox, button label, email subject and heading — every option ships with an inline recommendation, so you know what to pick and why.
- Double opt-in on by default — confirmed addresses only
- Consent wording you control (privacy-law friendly)
- Re-theme the form with
--acbis-*CSS tokens
Everything included
The full toolbox
Every capability shipped today — everything here is free except CSV export, the single Pro feature.
Variable products
The form reveals when a sold-out variation is selected, and notifies only that variation's waitlist.
Shortcode + block
Drop [acbis_back_in_stock_form] or a Gutenberg block anywhere — works where the WooCommerce hook does not fire.
Double opt-in
Optional email confirmation before a customer joins the list. On by default.
Consent checkbox
Optional explicit-consent box for privacy-law compliance, with your own wording.
Background sending
Emails go out through Action Scheduler in batches of 50 — hundreds of subscribers, no timeout.
One-click unsubscribe
A secure tokenized link in every email. No account, no login required.
Subscriber list
A per-product list in wp-admin with KPIs, status filters and email search.
Custom email text
Configurable subject and heading for confirmation and restock emails, with {product} and {store} placeholders.
Any restock vector
Manual edits, CSV imports, API/ERP sync, WP-CLI — every standard restock triggers a notification.
Anti-abuse built in
Nonce, honeypot and per-IP rate limiting. The IP is hashed, never stored in clear text.
CSV export
Export the full subscriber list — email, product, status and dates — to CSV. Pro.

The alternative
Versus notifying by hand
A customer who wanted to buy hit a sold-out product and left. The demand exists — most stores just have no way to bring that customer back.
| Capability | By hand | Back In Stock |
|---|---|---|
| A "Notify me" form on every sold-out product — and per variation | — | |
| Demand recorded where you can see it (list, KPIs, filters) | Notes & memory | |
| Restock email goes out the moment stock returns | When you remember | |
| Covers midnight restocks, CSV imports and API syncs | — | |
| Hundreds of waiting customers without timing out | — | batches of 50 |
| Opt-in confirmation and consent records | — | |
| One-click unsubscribe in every email | — | |
| Time spent per restock | Yours | Zero |
Every capability above ships in the free version. Pro only adds CSV export of the subscriber list.

FAQ
Before you ask
Does it work with variable products?
Yes. For variable products the form appears when the customer selects an out-of-stock variation, and it notifies only the people waiting for that specific variation — not everyone on the parent product.
Will it send hundreds of emails at once and time out?
No. Sending runs in the background through Action Scheduler (bundled with WooCommerce) in batches of 50, re-queuing automatically until everyone is notified. It also re-checks that the product is still in stock before each batch, so a stock that drops back to zero mid-send does not email a sold-out product.
Do my customers need an account?
No. They only leave an email. Confirmation and unsubscribe both work through secure tokenized links (256-bit tokens), so there is no login and no password anywhere in the flow.
Will it work with Bricks, Elementor, Divi or a block theme?
Yes. Besides the automatic WooCommerce hook, the form ships as a shortcode (
[acbis_back_in_stock_form]) and a Gutenberg block, both rendered by the same engine. So if your builder's product template does not fire the standard WooCommerce hook, you can place the form yourself anywhere on the page.Does it send my customers' data anywhere?
No. Restock emails are sent from your own site (
wp_mail / your SMTP), and your subscribers' data stays in your database. The IP used for anti-abuse rate limiting is stored hashed, never in clear text. The plugin only contacts Freemius for license validation and update checks — never with your customers' data, and only if you opt in or activate a license.What triggers a restock notification?
Any standard WooCommerce stock change back to "in stock": editing the product in wp-admin, a bulk CSV import, an inventory sync from an ERP or POS over the API, or WP-CLI. The plugin listens to WooCommerce's own stock hooks, so it does not matter how the stock came back.
What exactly is in Pro versus Free?
Free is the whole loop: the notify-me form on simple and variable products, double opt-in, consent, the automatic restock email, background sending, the subscriber list with filters, and one-click unsubscribe. Pro adds one thing: one-click CSV export of your subscriber list. No core feature is locked behind Pro.
Is the free version crippled? What's the catch?
No catch. The free version is a complete back-in-stock system for a real store — no subscriber cap, no daily quota, no nag screens. Pro adds CSV export for people who want to pull their list into a spreadsheet or another tool. We sell convenience, not the core promise.
Can I restyle the form to match my theme?
Yes. The button label is configurable in Settings, and the form exposes
--acbis-* CSS custom properties (accent, button colors) so you can re-theme it from your own stylesheet without touching the plugin.Is it WooCommerce HPOS compatible?
Yes. The plugin declares compatibility with WooCommerce High-Performance Order Storage. It does not touch orders — it stores subscriptions in its own table — but the declaration keeps WooCommerce's compatibility screen clean.
Can I get a refund?
14 days, no questions asked. Email info@australcode.io with your order number and the refund is issued through Freemius, our Merchant of Record.
